问题
I need to know which mail clients support the "automated labeler" email address format.
From research I have found only one: Gmail. They support labeled email addresses like:
- name+label_1@gmail.com
- name+label_2@gmail.com
- etc.
The above emails are unique but reference name@gmail.com with unique labels.
Follow this question and answer for more insight on this topic.
Note that the "automated labeler" isn't a GMail specific feature, Gmail simply popularised it.. Other mail servers support this feature, some using
+as the separator, others using-.
